Abstract (en)

[origin: WO9953364A1] The invention relates to a transversal electro optical modulator (10) which can be controlled by means of an electric amplifier, comprising at least two elements for modulating (11) the light wave of a laser beam, and can preferably be used for projection of TV images. The invention is characterized in that the modulator elements are arranged behind each other in relation to the laser beam, that a focusing device (14) is arranged both in front of and behind each modulator element, that an electric amplifier output (22, 23) is associated with each modulator element and that all electric amplifier (A) inputs (24, 25) are connected to the same control line (26) as the control signal.
